Question

(6) The front wall of a factory shown below has to be painted. The area of the entrance shown in grey does not need to be painted. If the cost of painting is €40 per square m, find the total cost for painting the entire wall.​

Answer 1

Answer:

€14400

Step-by-step explanation:

Area of the whole wall = L × B

                                      = 16m × 24 m

                                      = 384m²

Area of wall not to be painted = l × b

                                                  = 4m × 8m

                                                  = 24m²

∴ Area of the wall to be painted = Area of the whole wall - Area of wall not                      to be painted

= 384m²- 24m²

= 360m²

total cost of painting = 360 × €40

                                   = €14400
